[Tagging] roundabouts without obstacles in the middle

[Gerd Petermann]

I just notice that center_barrier or center_obstacle would
be US spelling, so it has to be centre_*

In other words, we should probably not use a key that is 
different in UK / US spelling, else we'll see many wrong
entries.

Another problem that I see here is that we allow to map 
a roundabout as multiple ways with the junction=roundabout 
tag. What would it mean if they don't all show the same 
values for the obstacle?

They are currently not - Most navigational software basically does
not know about mini-roundabouts because they are difficult to
preprocess (One needs to add ways).

I'd like mini_roundabouts to disappear and be replaced with
an additional tag on a roundabout which tells about the existance
of an obstacle in the middle which makes it one less special case.

junction=roundabout
center_obstacle=clear/yes/no/drivable
roundabout=flat/obstacle

Whatever ... So processing a roundabout is ALWAYS the same from the
navigational perspective and changes only from route selection when
your vehicle is getting longer.
